along Hayes Street and 4th Street West adjacent to the residential areas. The developer will also be responsible for completing the Hayes Street and 4th Street West road improvements along the length of the overall 5+/- parcel, including “off-site” road improvements north of the site adjacent to the hospital parking lot. Methods Prior to the field survey, we conducted a search of California Department of Fish and Wildlife’s (CDFW) California Natural Diversity Database (CNDDB, 2017). The CNDDB search included the USGS 7.5-minute Sonoma and Glen Ellen topographic quadrangles, which encompass approximately 120 square miles surrounding the project site. The United States Fish and Wildlife Service (USFWS) IPaCTrust Report of Federally Threatened and Endangered species that may occur in or be affected by projects in the project vicinity was also reviewed (Attachment B). This information was used to identify wildlife and plant species that have been previously documented in the project vicinity or have the potential to occur based on suitable habitat and geographical distribution. The USFWS on-line maps of designated critical habitat were also downloaded. A field survey was conducted on November 8, 2017. The survey consisted of walking throughout the site making observations of habitat conditions and noting surrounding land uses, general habitat types, and plant and wildlife species. The survey included an assessment of the site for presence or absence of potentially jurisdictional Waters of the U.S. (a term that includes wetlands) as defined by the ACOE (1987; 2008), special-status species, and suitable habitat for special-status species (e.g., salt marshes, vernal pools). Additionally, trees in and near the site were assessed for the potential use by nesting raptors and the site was also searched for burrowing owls (Athene cunicularia) or ground squirrel burrows that could be utilized by burrowing owls.
Sonoma Hospital Site: Biology 5 December 22, 2017
Results GENERAL SETTING: The site is located in Sonoma, in Sonoma County, California (Figure 1). The site is in an unnumbered Section, in Township 5 North, Range 6 West of the USGS 7.5-minute Sonoma topographic quadrangle (Figure 2). The site is essentially level and is at an elevation of approximately 65 feet above mean sea level. The north part of the site is a graveled area that appears to have been used for overflow parking in the past, and an open field that is routinely disked (Figure 3 and photographs in Attachment C). West MacArthur Street is located along the south edge of the site and Hayes Street bounds the site on the west. The Sonoma Valley Hospital parking lot bounds the site on the north and 4th Street West is located along the east edge of the site. Adjacent parcels primarily contain single-family homes; there is a retirement home, to the south of the site, across West MacArthur Street. VEGETATION: Natural habitats surrounding the project site have been entirely replaced by streets, homes, and generally highly landscaped areas. The body of the site is a periodically disked and/or mowed field vegetated in ruderal grass and weed species. California annual grassland best describes the disturbed upland grassland vegetation in the site. Oats (Avena sp.), foxtail barley (Hordeum murinum), soft chess (Bromus hordeaceus), ripgut brome (Bromus diandrus), and perennial ryegrass (Lolium perenne) are dominant grass species on-site. Other grassland species such as chickory (Cichorium intybus), mustard (Brassica sp.), mallow (Malva neglecta), prickly lettuce (Lactuca serriola), and morning glory (Convolvulus arvensis) are intermixed with the grasses. The only tree in the site is an English walnut (Juglans regia), which is located in the southeast part of the site (Figure 3 and photographs in Attachment C). There are numerous primarily non-native landscape trees in the parcels surrounding the site, and some relatively small ornamentals in the Sonoma Valley Hospital parking lot.

WILDLIFE: Only a few bird species were observed in the site during the recent survey. These include western kingbird (Tyrannus verticalis), mourning dove (Zenaida macroura), western scrub jay (Aphelocoma coerulescens), and Brewer’s blackbird (Euphagus cyanocephalus). The on-site walnut and other relatively large trees near the site are suitable for nesting raptors and other protected migratory birds. Given the presence of some trees and raptor foraging habitat (i.e., open fields) in and near the site, it is possible one or more pairs of raptors, plus a variety of songbirds, nest in trees in or near the site each year. Further, it is considered likely that songbirds nest within trees, shrubs, and grassland habitats in and adjacent to the site each year. Only a few mammals common to urban areas have potential to occur in the site and no mammals were observed during the field survey. Striped skunk (Mephitis mephitis), black-tailed hare (Lepus californicus), desert cottontail (Sylvilagus audubonii), Virginia opossum (Didelphis virginiana), and California ground squirrels (Spermophilus beecheyi) are expected to occur in the project site on occasion. No ground squirrel burrows were observed in the site. Due to lack of suitable habitat and the location of the site in town, few amphibians and reptiles are expected to use habitats in the site. No reptiles or amphibians were observed during the recent survey. Common species such as western fence lizard (Sceloporus occidentalis) and Pacific chorus frog (Pseudacris regilla) may occur in the site. WATERS OF THE U.S. AND WETLANDS: Waters of the U.S., including wetlands, are broadly defined under 33 Code of Federal Regulations (CFR) 328 to include navigable waterways, their tributaries, and adjacent wetlands. State and federal agencies regulate these habitats and Section 404 of the Clean Water Act requires that a permit be secured prior to the discharge of dredged or fill materials into any waters of the U.S., including wetlands. Both CDFW and ACOE have jurisdiction over modifications to riverbanks, lakes, stream channels and other wetland features.
Sonoma Hospital Site: Biology 8 December 22, 2017
“Waters of the U.S.”, as defined in 33 CFR 328.4, encompasses Territorial Seas, Tidal Waters, and Non-Tidal Waters; Non-Tidal Waters includes interstate and intrastate rivers and streams, as well as their tributaries. The limit of federal jurisdiction of Non-Tidal Waters of the U.S. extends to the “ordinary high water mark”. The ordinary high water mark is established by physical characteristics such as a natural water line impressed on the bank, presence of shelves, destruction of terrestrial vegetation, or the presence of litter and debris. Jurisdictional wetlands and Waters of the U.S. include, but are not limited to, perennial and intermittent creeks and drainages, lakes, seeps, and springs; emergent marshes; riparian wetlands; and seasonal wetlands. Wetlands and Waters of the U.S. provide critical habitat components, such as nest sites and a reliable source of water, for a wide variety of wildlife species. No potentially jurisdictional wetlands or Waters of the U.S. were observed in the site. The site consists of upland grassland habitats that are highly disturbed. Interestingly, a small creek that is piped under the neighborhoods to the north of the overall 5+/- acre parcel daylights along the east side of 4th Street West, just east of and across the street from the north part of the Sonoma Valley Hospital parking lot. The creek flows east between residential subdivisions, drains into Schell Creek, and eventually drains in to Sonoma Creek several miles south of the site. Development of the project for residential uses, and completion of road improvements along Hayes Street and 4th Street West will not involve any work in this off-site creek. SPECIAL-STATUS SPECIES: Special-status species are plants and animals that are legally protected under the state and/or federal Endangered Species Act or other regulations. The Federal Endangered Species Act (FESA) of 1973 declares that all federal departments and agencies shall utilize their authority to conserve endangered and threatened plant and animal species. The California
Sonoma Hospital Site: Biology 9 December 22, 2017
Endangered Species Act (CESA) of 1984 parallels the policies of FESA and pertains to native California species. Special-status species also include other species that are considered rare enough by the scientific community and trustee agencies to warrant special consideration, particularly with regard to protection of isolated populations, nesting or denning locations, communal roosts, and other essential habitat. The presence of species with legal protection under the Endangered Species Act often represents a major constraint to development, particularly when the species are wide-ranging or highly sensitive to habitat disturbance and where proposed development would result in a take of these species. Special-status plants are those which are designated rare, threatened, or endangered and candidate species for listing by the USFWS. Special-status plants also include species considered rare or endangered under the conditions of Section 15380 of the California Environmental Quality Act Guidelines, such as those plant species identified on Lists 1A, 1B and 2 in the Inventory of Rare and Endangered Vascular Plants of California (CNPS, 2017). Finally, special-status plants may include other species that are considered sensitive or of special concern due to limited distribution or lack of adequate information to permit listing or rejection for state or federal status, such as those included on CNPS List 3. The likelihood of occurrence of listed, candidate, and other special-status species in the site is generally low. Table 1 provides a summary of the listing status and habitat requirements of special-status species that have been documented in the greater project vicinity or for which there is potentially suitable habitat in the greater project vicinity. This table also includes an assessment of the likelihood of occurrence of each of these species in the site. The evaluation of the potential for occurrence of each species is based on the distribution of regional occurrences (if any), habitat suitability, and field observations.

Sonoma Hospital Site: Biology 17 December 22, 2017
SPECIAL-STATUS PLANTS: Fifteen (15) species of special-status plants were identified in the CNDDB (2017) search: Franciscan onion (Allium peninsulare var. franciscanum), Napa false indigo (Amorpha californica var. napensis), big-scale balsamroot (Balsamorhiza macrolepis var. macrolepis), Sonoma sunshine (Blennosperma bakeri), narrow-anthered California brodiaea (Brodiaea californica var, leptandra), Rincon Ridge ceanothus (Ceanothus confusus), Sonoma ceanothus (Ceanothus sonomensis), dwarf downingia (Downingia pusilla), fragrant frittilary (Fritillaria liliacea), congested-headed hayfield tarplant (Hemizonia congesta ssp. congesta), thin-lobed horkelia (Horkelia tenuiloba), legenere (Legenere limosa), Jepson’s leptosiphon (Leptosiphon jepsonii), Cobb Mountain lupine (Lupinus sericatus), and oval-leaved viburnum (Viburnum ellipticum). (Table 1 and Attachment A). Sonoma sunshine is the only special-status plant in the USFWS IPaC Trust Report. No special-status plants or suitable habitat for special-status plants were observed in the site. Special-status plants generally occur in relatively undisturbed areas in vegetation communities such as chaparral, vernal pools, marshes and swamps, seasonal wetlands, woodlands, and areas with unusual soils. Most of the species in Table 1 occur in one of these unique habitat types that are not present on-site. In contrast, the site is disturbed upland grassland that is not suitable for any special-status plant species. Due to lack of suitable habitat, it is unlikely that special-status plants occur in the site. SPECIAL-STATUS WILDLIFE: The potential for intensive use of the site by special-status wildlife species is low. Special-status wildlife species recorded in project area in the CNDDB (2017) query include northern spotted owl (Strix occidentalis caurina) western yellow-billed cuckoo (Coccyzus americanus occidentalis), white-tailed kite (Elanus leucurus), bank swallow (Riparia riparia), burrowing owl, San Pablo song sparrow (Melospiza melodia samuelis), golden eagle (Aquila chrysaetos), black swift (Cypseloides niger), grasshopper sparrow (Ammodramus savannarum), yellow rail (Coturnicops noveboracensis), American badger (Taxidea taxus), pallid bat (Antrozous pallidus), California tiger

salamander (Ambystoma californiense), California red-legged frog (Rana auroura draytonii), foothill yellow-legged frog (Rana boylii), western pond turtle (Emys marmorata), red-bellied newt (Taricha rivularis), California giant salamander (Dicamptodon ensatus), Central Coast steelhead (Oncorhynchus mykiss), and California freshwater shrimp (Syncaris pacifica). Salt-marsh harvest mouse (Reithrodontomys raviventris), green sea turtle (Chelonia mydas), San Bruno elfin butterfly (Callophrys mossii bayensis) and delta smelt (Hypomesus transpacificus) are not recorded in the CNDDB (2015) within the search area, but are on the USFWS IPaC Trust Report (Attachment B). While the project site may have provided habitat for special-status wildlife species at some time in the past, development has substantially modified natural habitats in the greater project vicinity, including those within the site. None of the wildlife species identified in the CNDDB have the potential to occur in the site on more than a transitory or very occasional basis. Special-status birds may fly over the area on occasion, but would not be expected to nest in the project site. Special-status bats may also fly over the area on occasion, but would not be expected to roost in the site. The site does not provide aquatic habitat for Central Coast steelhead, delta smelt, any other species of special-status fish, or California freshwater shrimp. The site also does not provide aquatic habitat required by California red-legged frog, foothill yellow-legged frog, California tiger salamander, California giant salamander, red-bellied newt, green sea turtle, or western pond turtle. The site does not provide suitable denning habitat for American badger and there is no coastal scrub habitat in the site for San Bruno elfin butterfly. CRITICAL HABITAT: The site is not in designated critical habitat of any federally listed species (Attachment D). There is a polygon of designated critical habitat for California red-legged frog (USFWS, 2006) several miles west of the site a polygon of designated critical habitat for Northern spotted owl (USFWS, 2012) a
Sonoma Hospital Site: Biology 19 December 22, 2017
few miles northeast of the site (Attachment D). Several rivers and creeks in the area are designated critical habitat for Central Coast steelhead (NOAA, 2005). Conclusions and Recommendations
• The site is disturbed upland grasslands, an old gravel parking area, and a single walnut tree. There are no sensitive habitats in the site; the site is biologically unremarkable.
• There are no potentially jurisdictional Waters of the U.S. or wetlands in the
site. • Due to a lack of suitable habitat, it is unlikely that special-status plants
occur in the site. • Due to a lack of suitable habitat and location in an urban setting, no
special-status wildlife species are expected to occur in or near the site on more than an occasional basis.
• The site is not within designated critical habitat for any federally listed
species. • The tree and grasslands in the site may be used by nesting birds
protected by the Migratory Bird Treaty Act of 1918 and Fish and Game Code of California. If vegetation removal and/or project construction occurs between February 1 and August 31, a pre-construction nesting bird survey is recommended. If active nests are found within the survey area, vegetation removal and/or project construction should be delayed until a qualified biologist determines nesting is complete.

IPaC resource listThis report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources)under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below.The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly a�ected byactivities in the project area. However, determining the likelihood and extent of e�ects a project may have on trust resources typically requiresgathering additional site-speci�c (e.g., vegetation/species surveys) and project-speci�c (e.g., magnitude and timing of proposed activities)information.
Below is a summary of the project information you provided and contact information for the USFWS o�ce(s) with jurisdiction in the de�nedproject area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWIWetlands) for additional information applicable to the trust resources addressed in that section.

Endangered speciesThis resource list is for informational purposes only and does not constitute an analysis of project level impacts.
The primary information used to generate this list is the known or expected range of each species. Additional areas of in�uence (AOI) forspecies are also considered. An AOI includes areas outside of the species range if the species could be indirectly a�ected by activities in thatarea (e.g., placing a dam upstream of a �sh population, even if that �sh does not occur at the dam site, may indirectly impact the species byreducing or eliminating water �ow downstream). Because species can move, and site conditions can change, the species on this list are notguaranteed to be found on or near the project area. To fully determine any potential e�ects to species, additional site-speci�c and project-speci�c information is often required.
Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listedor proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensedby any Federal agency. A letter from the local o�ce and a species list which ful�lls this requirement can only be obtained by requesting ano�cial species list from either the Regulatory Review section in IPaC (see directions below) or from the local �eld o�ce directly.
For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an o�cial species list by doingthe following:
1. Draw the project location and click CONTINUE.2. Click DEFINE PROJECT.3. Log in (if directed to do so).4. Provide a name and description for your project.5. Click REQUEST SPECIES LIST.
Listed species are managed by the Ecological Services Program of the U.S. Fish and Wildlife Service.

no data survey e�ort breeding season probability of presence
Probability of Presence SummaryThe graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This informationcan be used to tailor and schedule your project activities to avoid or minimize impacts to birds.
Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in your project's counties during a particular week of the year. (A year isrepresented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey e�ort (see below) can be used toestablish a level of con�dence in the presence score. One can have higher con�dence in the presence score if the corresponding survey e�ortis also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected dividedby the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee wasfound in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability ofpresence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relativeprobability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fallbetween 0 and 10, inclusive. This is the probability of presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season ( )Yellow bars denote when the bird breeds in the Bird Conservation Region(s) in which your project lies. If there are no yellow bars shown for abird, it does not breed in your project area.
Survey E�ort ( )Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the counties ofyour project area. The number of surveys is expressed as a range, for example, 33 to 64 surveys.
To see a bar's survey e�ort range, simply hover your mouse cursor over the bar.
No Data ( )A week is marked as having no data if there were no survey events for that week.
Survey TimeframeSurveys from only the last 10 years are used in order to ensure delivery of currently relevant information.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Such measures areparticularly important when birds are most likely to occur in the project area. To see when birds are most likely to occur in your project area, view the Probability ofPresence Summary. Special attention should be made to look for nests and avoid nest destruction during the breeding season. The best information about whenbirds are breeding can be found in Birds of North America (BNA) Online under the "Breeding Phenology" section of each species pro�le. Note that accessing thisinformation may require a subscription. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type ofinfrastructure or bird species present on your project site.
What does IPaC use to generate the migratory birds potentially occurring in my speci�ed location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) that might be a�ected by activities in your project location. Thesebirds are of priority concern because it has been determined that without additional conservation actions, they are likely to become candidates for listing under theEndangered Species Act (ESA).
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growingcollection of survey, banding, and citizen science datasets. The AKN list represents all birds reported to be occurring at some level throughout the year in thecounties in which your project lies. That list is then narrowed to only the Birds of Conservation Concern for your project area.
Again, the Migratory Bird Resource list only includes species of particular priority concern, and is not representative of all birds that may occur in your project area.Although it is important to try to avoid and minimize impacts to all birds, special attention should be made to avoid and minimize impacts to birds of priorityconcern. To get a list of all birds potentially present in your project area, please visit the E-bird Explore Data Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my speci�ed location?
The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derivedfrom a growing collection of survey, banding, and citizen science datasets.
Probability of presence data is continuously being updated as new and better information becomes available.
How do I know if a bird is breeding, wintering, migrating or present year-round in my project area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the followingresources: The The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab ofOrnithology Neotropical Birds guide. If a bird entry on your migratory bird species list indicates a breeding season, it is probable the bird breeds in your project'scounties at some point within the time-frame speci�ed. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area.

Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of theseresources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identi�ed based on vegetation, visible hydrology and geography. Amargin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries orclassi�cation established through image analysis.
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data andthe amount of ground truth veri�cation work conducted. Metadata should be consulted to determine the date of the source imagery used and any mappingproblems.
Wetlands or other mapped features may have changed since the date of the imagery or �eld work. There may be occasional di�erences in polygon boundaries orclassi�cations between the information depicted on the map and the actual conditions on site.
Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detectwetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastalwaters. Some deepwater reef communities (coral or tuber�cid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, goundetected by aerial imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may de�ne and describe wetlands in a di�erent manner than that used in this inventory.There is no attempt, in either the design or products of this inventory, to de�ne the limits of proprietary jurisdiction of any Federal, state, or local government or toestablish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modi�cations within oradjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning speci�ed agency regulatory programs and proprietaryjurisdictions that may a�ect such activities.
